"Dead end" exits

[Roadrunner75]

The Garden State Arts Center in Holmdel, NJ is only freeway accessible from the Garden State Parkway.  There may be service roads connected to the street system of Holmdel, but not open to the GP.  So Exit 116 on the GSP serves no other function, but to access the Arts Center, the commuter lots, the Vietnam Memorial, and Telegraph Hill Park.

There is a 'secret' entrance along Crawford's Corner Road, located here:

It's actually marked as a commuter parking entrance, similar to some of the other secret Parkway entrances at rest areas, while at the same time also marked as GSP "Official Business Only".  I used this recently to enter the parking lot for a concert at the Arts Center, but I'm not sure if my car and the other 5 cars or so that entered at the same time just got lucky that it was only an attendant near the entrance rather than one of the many State Troopers roaming the lots.  Since the State Police barracks is right at the entrance, I probably wouldn't use this as a regular cut-through to the GSP.  I have seen troopers occasionally monitor the secret entrances at rest areas which are marked for commuter parking only.

The Robert Moses Causeway has a dead end exit on Captree Island, There are a few houses on the island, but the only way off it is through the same ramps that brought you there.

Kind of stretching this, but there are three exits on I-190 just outside of Buffalo that are only connected to the rest of the world via the Interstate and its toll bridges. The town of Grand Island, NY is only accessible via I-190 exits 18, 19, and 20 and footpaths on the Interstate's river bridges. Drivers, including residents, must pay a $1 toll to the NYSTA to cross the bridges and get onto the island.

How about the "Cattle Pens" exit on the Kansas Turnpike?

Google Maps shows an access road heading south out of the cattle pen area, but I don't think it's open to the public.
